Description Junqi Zhao 2018-04-26 03:18:51 UTC 
Description of problem:
openshift_prometheus_node_exporter_install default value is true, it is better to change to false, since prometheus_node_exporter pods are mainly used by online monitoring team, they can set it to true if they want to deploy prometheus_node_exporter pods.

roles/openshift_prometheus/README.md:- `openshift_prometheus_node_exporter_install`: true (default) or false
roles/openshift_prometheus/defaults/main.yaml:openshift_prometheus_node_exporter_install: true
roles/openshift_prometheus/tasks/main.yaml:  when: openshift_prometheus_node_exporter_install | default(true) | bool
